864 Pc Roll-on No-leak roller-ball inserts replacements 5 or 10ml Empty bottle

Description

HELLO!
864Pc set of roller ball fitments/ inserts.
This is for 1 case/ 6 grosses of roll-on bottles.  If you mix your own essential oils, the blend shouldn't be more than 30% of the total volume in the bottle. That's the way roller ball containers are designed for.
These are normally pricey to buy in bulk, but we have a surplus!
Every manufacturer of bottles is different, so if its hard to push in try this:
put the bottle on a firm surface, place the roller ball in the bottle. Place the cap on top and with firm downward pressure, holding bottle in hand,  turn the cap clockwise and the rollerball will easily go in.  IT similar to screwing a kid onto a mason jar. (this is from bottling perfumes for many decades)
